The HEVC decoder will start setting stereoscopic view position (left or
right) based on 3D Reference Displays Info SEI message in future
commits. This information should be merged with container-derived
stereo3D side data.
Only do it in reget_buffer().
The purpose of this clearing this flag is to prevent it for
unintentionally persisting across multiple invocations of this function
on one frame, however that is only a problem if the frame is not
unreffed between uses, which is only the case with reget_buffer().
In other cases the caller may legitimately want to set the discard flag
and should have the option of doing so.
The per-frame reference picture set contains two more lists -
INTER_LAYER[01]. Assuming at most two layers, INTER_LAYER1 is always
empty, but is added anyway for completeness.
When inter-layer prediction is enabled, INTER_LAYER0 for the
second-layer frame will contain the base-layer frame from the same
access unit, if it exists.
The new lists are then used in per-slice reference picture set
construction as per F.8.3.4 "Decoding process for reference picture
lists construction".

| vkCmdEncodeVideoKHR(): The currently configured encode quality level (2) for
VkVideoSessionKHR 0x8f000000008f[] does not match the encode quality level (0)
VkVideoSessionParametersKHR 0xfd00000000fd[] was created with. The Vulkan spec
states: The bound video session parameters object must have been created with
the currently set video encode quality level for the bound video session at the
time the command is executed on the
device (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkCmdEncodeVideoKHR-None-08318)
This patch adds a new function helper for creating session parameters, which
also sets the quality level and it's called by the H.264 and H.265 Vulkan
encoders.
It's unnecessary as the entire struct is written to immediately after it's
allocated.
Restores the behavior prior to fec6a8df31.

This commit adds the first Vulkan hardware encoder.
Currently, P, and **B**-frames are supported. This marks the
first implementation to support both.
The encoder has feature-parity with VAAPI.
This commit adds the common Vulkan video encoding framework.
It makes full use of the asynchronous features of our new common
hardware encoding code, and of Vulkan.
The code is able to handle anything from H264 to AV1 and MJPEG.
ff_vvc_output_frame is called before actually decoding. It's possible
for ff_vvc_output_frame to select current frame to output. If current
frame is nonref frame, it will be released by ff_vvc_unref_frame.
Fix this by always marking the current frame with
VVC_FRAME_FLAG_SHORT_REF, as is done by the HEVC decoder.
